I purchased a sealed iPod Touch on eBay and after only one day of usage, there are at least 4 or 5 particles of dust stuck under my screen. What's more annoying is that some of them are stuck right in the middle of the screen. I don't live in a dusty environment and I didn't even take this iPod out. Some people are saying this is due to a manufacturing problem. The warranty for this iPod ends in 2009 and I was wondering if I can go to my local Apple Store to exchange it for a different one.
